:mod:`spwd` --- The shadow password database
|
|
============================================
|
|
|
|
.. module:: spwd
|
|
:platform: Unix
|
|
:synopsis: The shadow password database (getspnam() and friends).
|
|
|
|
--------------
|
|
|
|
This module provides access to the Unix shadow password database. It is
|
|
available on various Unix versions.
|
|
|
|
You must have enough privileges to access the shadow password database (this
|
|
usually means you have to be root).
|
|
|
|
Shadow password database entries are reported as a tuple-like object, whose
|
|
attributes correspond to the members of the ``spwd`` structure (Attribute field
|
|
below, see ``<shadow.h>``):

The sp_namp and sp_pwdp items are strings, all others are integers.
|
|
:exc:`KeyError` is raised if the entry asked for cannot be found.
|
|
|
|
The following functions are defined:
|
|
|
|
|
|
.. function:: getspnam(name)
|
|
|
|
Return the shadow password database entry for the given user name.
|
|
|
|
.. versionchanged:: 3.6
|
|
Raises a :exc:`PermissionError` instead of :exc:`KeyError` if the user
|
|
doesn't have privileges.
|
|
|
|
.. function:: getspall()
|
|
